“…Hence the formation of hydrocarbon, carbon monoxide, and carbon dioxide during the combustion can be completely avoided; however a trace amount of these compounds may be formed due to the partial burning of lubricating oil in the combustion chamber [22]. However hydrogen cannot be used as a sole fuel in a compression ignition (CI) engine, since the compression temperature is not enough to initiate the combustion due to its higher self-ignition temperature [23]. Hence hydrogen cannot CI engine without the assistance of a spark plug or glow plug.…”

“…For the constant specific volume line and known temperature determine the specific entropy per mole combustion gases at state (3). Isentropic expansion from state (3) to state (4) with known specific volume 4 v is iterated using Equation (15) for excess air factor λ = 1.5 and an initial guess lower than T 4 lower than T 3 . With the temperature T 4 progressively decreased until 4 3 0.001…”

“…Significance is being attached to hydrogen in view to its CO 2 free combustion, its properties and due to the fact that it can be produced from various feed stocks including renewable energy sources [3]. Though nitrogen oxides (NO x ) emissions are formed upon hydrogen combustion, it can be minimized to low concentrations compared with hydrocarbon fuels [4].…”

Fast depletion of fossil fuels with its resources already passed its mid depletion region and the pollution levels already reached unsafe levels which make it utmost necessity to search for alternative fuels to meet sustainable energy demand with minimum environmental impact. Among alternative fuels, hydrogen is considered as the near future, long term renewable, sustainable and non-polluting fuel. In the present paper, hydrogen fueled internal combustion engine fundamentals highlighted and presented relating to hydrogen combustion properties. A Mat lab programmed hydrogen temperature-entropy-energy chart is developed and presented for fresh charge and products of combustion at different excess air factors per mole combustion gases. The chart, then, used to represent a SI hydrogen-fueled fuel/air cycle analysis, which proved to be valuable design tool for engine sizing and for prediction of engine performance. Predictions carried out using the hydrogen F/A cycle analysis at different λ show low brake specific fuel consumption and low volume specific power compared with conventional SI engine.

“…The major energy is obtained from diesel while the rest of the energy is supplied by hydrogen. Adding hydrogen to diesel engine that operate primary by combusting diesel fuel has showed a significant improvement in engine efficiency (around 20%) [2] when compared to pure diesel combustion and an increase of 13% in NOx emission. Masood et al [3] reported a brake thermal efficiency of 30% when hydrogen is used in the dual fuel mode with diesel at a compression ratio of 24.5.…”

Abstract.This experimental study evaluates the feasibility of supporting compression ignition engine that primary run on diesel fuel with hydrogen gas that is produced by solar-hydrogen cycle. A photovoltaic panel is used to produce hydrogen through electrolysis from solar energy. Different mass ratio of hydrogen enrichment to liquid diesel fuel are tested on an engine operating under fixed torque of 14.7 N-m and engine rotational speed of 1100 rpm. Under same loading condition, the study shows that hydrogen can be used to reduce diesel fuel consumption and CO2 emission however this comes on the cost of increasing of NOx emission. The results show that beyond a maximum mass ratio of hydrogen-to-diesel of 9.7%, the engine starts knocking. The experiment shows that adding hydrogen to the air intake of a diesel requires a simple pluming operation in which hydrogen is allowed to enter the engine from the air intake manifold and hence the cost of retrofitting of current diesel engine is considered marginal.
